I have always used (since 3.3?) "has_content" to check if an attribute has any content.

So your code would read:

{section show=$parent.object.data_map.site_image.has_content}
{attribute_view_gui attribute=$parent.object.data_map.site_image}
{section-else}
{attribute_view_gui attribute=$grand.data_map.site_image}
{/section}

Cheers

first, thanks alot for your help.
but unfortunately it is not working.
the first part of the code is working fine, if the parent has content it is displayed,
but the other case (if parent is empty) it never displayes anything in the section else

thanks alot.

It's probably not working because $grand is not set. You are setting this to the grandparent aren't you?

Try adding {$grand|attribute(show,2)} to the template to see what value it has. Also turning on debugging will really help as it will tell you if you are tring to access variables that do not exist etc.

I do understand what you mean very well, but i noticed that it doesn't display anything in the section else even any static content
like that:

{section show =$parent.object.data_map.site_image.content.is_empty|not}
{attribute_view_gui attribute=$parent.object.data_map.site_image}
{section-else}
1251
{/section}

even that static content is not displayed.

You have 

{section show =$parent.object.data_map.site_image.content.is_empty|not}

I supplied 

{section show=$parent.object.data_map.site_image.has_content}

If you have made that change and simply cut n' pasted the wrong code and it's still not working, post the debug output.

Cheers
